Apparatus for depositing thin film on wafer

摘要

A thin film deposition apparatus that can effectively use a chemical source having a high vaporization temperature is provided. The thin film deposition apparatus includes a chamber for depositing a thin film on a wafer, a canister for accommodating a liquid chemical source to be supplied to the chamber, and a vaporizer for vaporizing the liquid chemical source bubbled in the canister and providing the vaporized chemical source to the chamber. The vaporizer is installed on a top surface or lateral surface of the chamber by an adaptor block to be incorporated into the chamber. A first gas line between the vaporizer and the chamber is formed within the adaptor block.
